如何用g ++编译独立的可执行文件？

Question

I devellop a piece of c++ software on my OpenSUSE, which I like to test on another OpenSUSE system.

I copied the executable file on the other system, but when I am starting it I receive an error:

"error while loading shared libraries: libboost_system.so.1.61.0: cannot open shared object file: No such file or directory"

How can I compile an independent executable without dependencies?

Eclipse does this:

You need to make sure you have the boost libraries installed on your system, and that the path to them is included in you LD_LIBRARY_PATH variable.

For example, if the libboost_system.so file (or symlink) is to be found at /usr/local/boost-1.56.0/lib64 on your system, then you would run the command.

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/boost-1.56.0/lib64`

To find out exactly which libraries you need, you can run the command:

ldd my_binary

The output will tell you exactly which libraries are required, and which of those can't currently be resolved.
